'-Be it known that" I, SAMUEL'M. LANesToN,

a citizen of the United States, and a resident of Camden, 111- the county of Camden and State of New Jersey, have invented a new- "and Improved Machine for lViakin'g- Cellular Boards, of-Which thefollowingis a full,

clear,- and exact description;

1 This mvent onrelates to certain improvethe'crowns of'the corrugations. Tho single ments in machines for making cellular v board, and more particularly to thattype of;

machine in which one sheet of material is ,eorrugated and a'se'cond sheet .isglud' or pasted-to the crowns of the corrugations of 'the first sheet. In'iny present construction;

- the machine is especially adapted for mak ing asbestos board, and involves mechanism I for pasting together-two 'sheets,-eorrugating the combined sheets, heating-them to dry the adhesive material and isetain the corrugations in permanent form, and then'securing'. a third. shet'to'the crowns of the corru gations o'f the double corrugated sheet. a The object ofthe'invention is to provide- ;.hesive;

ainachine ii which all of the operations necessary in the'for-mation of single-faced ce1 i .lular. board may be carried'out, and in which the relative speeds of the be suitably controlled.

The special form oil machine illustratedin the accompanying drawings is designed for forming a cellular board: of asbestos, but the material need not necessarilvbe asbestos,

for it is evident that 'themachlne may he used for forming cellular board. of any other I are adapted to run at uniform speed, and.tl'1o suitable material; The corrugatin'g rollers speed of the feeding, pasting, and winding mechanisms may be. varied in res mct-thereto, so that'the depths of the corrugations may be varied. and the continuity of the ac t1on mamta ned.

The operation may be subdivided into. three separate steps nameh the pasting together of two sheets. the col-ruigating of the combined sheetresult'ing therefrom, and the applying of 'a third sheet to machine carries on' all of these separate steps successively.

For carryingon the first step of the operatieil. I have illustrated the machine as pro- \ided i'ylth a fra 'ne or standard '10, adapted to support a tankor tray 11 for the ad-.

hesive material. This adhesive material is preferablysilicate .of soda, .but any other composition desired .may beemplo 'ed;-

igAbove-the tank or tray is mounted a. pastc applying-roller 12, over' which one sheet A of 'the material .may pass, and this roller contacts with a transferring roller-13,- the ltnyer portion of which dips into the" ad The frame, at one side thereof, carries o11tnardlvextendiing. arms. l-l for supporting the roll B from which thesheet A. is delivered, and the'auxiliary frame whichsnpports the pasting roller 12 mayv also support :arms '15, having aroller 16',

aft-their outer ends for resting directlynpou the outer-surface of the sheet ,A', intermediate the 'roll B and the .pastie-a pl 'ing roller 12, so as to maintain; thesheetsubstantially taut..

The frame or standard 10 carries a bracket or auxiliary "frame upon the sidethereof .oppOsItet tHe arms 14, and tlns auxiliary frame serves tosupport the mechamsmior combined. sheet and to support oncend'of' a steam chest. Thefeeding mechanism inchides tworollers 18' and 19, theformcr of which is mounted within hearings on the anxiliary frame-17' and thelatter of which is carried:v by pivoted arms 2Q. ,Tlie'two' arms are pivoted on a shaftwlhch also car-21f 'lfli riesa roller -91.- mwhim the second hcet C passesQuThe upper surface of the roller 'is axslight distance .belowgthe under=-surface of thelsheet ..so that the sheets A and C asthey pass to the feed rollers 18 and. '19, are elnselyadjacent each other;

l o? varviiw the enga ementof. the feedingrollers 18 and 19 with the sheets A and C,

' .'a pplying=a'-seeond sheet to the adhesive co'vered surface of the sheet-A5 'to feed the so as to rmit a slight slipping should emand, one of the arms 20 is,

a 'depending rod 23, at its outer or free end.

The rod is secured at its lower end-to a foot lever 24, so constructed that by pressing upon said lever, the rod may be pulled downwardly and the roller 19 raised-away from the roller 18.' The sheet C may be delivered to the roller 21 from any sultable source below said roller, but preferably from a roll of ,material D, supported on small standards 25 adjacent the frame 10..

For driving the feeding rollers and the paste-applying rollers :at the same speed, and for varying,this speed, the auxiliary frame 17 carries at its outer end gear meeh-- anism substantially as shown in Figs. 2 and 5. A shaft 26 is mounted in suitable bearingsin the auxiliary frame, and this shaft is driven at constant speed bya chain- 27.

Upon the opposite 'end' of the shaft from said chain there is 'mounted a'gear wheel 28 and a plate 29 pivoted to rock upon said shaft as atcenter. The plate 29 carries two gear wheels 30 and 31, both of which are continuously in mesh with the gear wheel 28, and upon the stub'shaft of each of these gear-wheels 30 and 31, may" be detachably secured pinions-32 and 33, respectively. On the" shaft of the lower feed roller '18 is mounted a inion- 34', which may mesh with- 'either the p nion 32 or the pinion 33. With the parts in the position indicated in Fig. 5, the gear 28, which rotates continuously at constant speed drives the gear 31 and motion is transmitted from this gear to the lower feed roller through the inions 33 and 3 1. The pinion 34 is of di erent size and the feed rollers driven at any speed desired inrespect to the constant speed of the gear- 28. At the opposite end of the roller 18 from the pinion 34:, there is mount- ((l' a sprocket wheel 35, and from this sprocket wheel a chain 36 transmits motion to a sprocket wheel 37 carried byv a shafti38 on the frame 10. Inter-meshing gears on the shaft and the shaft of the adhesive-feeding roller 13, serve to drive the latter at the same speed as the feeding rollers 18 and 19. It will thus be noted that the frame 10 supports the mechanism for carrying on the first sic-p of the process. That is, coating on:- m-i's-.-e of the sheet of material with an adheslve, applying a second sheet thereto, feeding the combined sheet to the next portion ofthe apparatus, driving the feeding and adhesive-applying mechanism at the same speed, and varylng said speed.

The second main step of the processc'onsists in corrugating the combined sheets A and C, hereinafter referred 'to as the sheet E, and for accomplishing this, I providea frame 39, supporting at its upper end three corrugating rollers 10, 41 and 42. The cen tral one of these, 41, is mounted in suit-able bearings, While the two outer ones 40 and 42 are mounted in bearingsslidable in respect to the central corrugating roller, so that the teeth or corrugations of the rollers may intermesh at different distances to vary the extent O'f' the corrugations produced. These rollers are all hollow, as are also their supporting shafts, and during the operation,

steam-is, delivered from any suitable source "o the interiors of the several rollers, to maintain them at a high temperature, and lit thoroughly dry the material and harden and solidify the paste, or other adhesive, so that when. the material leaves the corrugating rollers, the corrugations will be permanentlyretained. The rollers are so mounted that the sheet E first engages with the lower side of the roller 40 and passes upwardly between the rollers 40' and 41, followstheupper surface of the roller 41, passes downwardly between the rollers 41 and 4:2, and the complete corrugated sheet F leaves the lower side of the roller 42 in substantially thesame plane as that of the uncorrugated sheet E. In order to insure the 'corrugatedsheet following the upper surface of the roller 41, I provide one or more Weights or guiding blocks 43, resting'directly upon the upper surface of the material above the roller 11 and having the under surface curved to correspond'with the curvature of the. roller and the material.

The roller 40 is provided witlr annular grooves 14; corresponding to the guiding blocks 43, and each guiding block carries a guiding-finger or pointed' projection 45 extending into the correspondinggroove lel and, down through between the rollers a sufa steam chest 46, disposed intermediate the frames 17 and 39, and preferably supported thereby.. The upper surface of this steam chest is in substantially the same plane. as the line of intersection of the two feeding rollers, so that it receives the combined sheet- E di'rtctly therefrom, and said steam chest terminates adjacent .the frame 39, so

that the combined sheet as soon as it leaves said steam chest, goes directlyto the 'corru gating rollers. The' length of r the steam 1 chest may be varied'at will, depending upon.

the nature of the adhesive 7 materialcmployed,.the time required to dry the adhesire, and the sr ed at which the machine is operated;

F or driving lie central corrugating roller 4-1 at a constant speed, I provide-the shaft of said roller with a. gear wheel .47, intermeshing with a pinion on a. main drive shaft 48, disposed directly above said cor'rugating roller. Power may be delivered to this main shaft 4-8 from any suitable source, and from" this shaft the 'entire machi' e is operated; The corrugating rollers"4;0 and42 are no; rectly driven hi t are" indirectlydi, venthrough their roller- 4:1.v A

For transmitting motion to the gear wheel engagement with :the central 28, I mount 'a shaft 49 inthe lower portionof the frame '39" and directly drive this shaft,

fromfthe shaft of the roller 41 by a. chain-:50.

The shaft 49 carries not only the sprocket wheel for the chain 5O, but also thesprocket 26. Tlierefore, the 'c'orrngating "rollers and thefs'haft 26 are driven at constant speed,v

While the adhesive-applying, roller 13 and the feeding rollers 18 and 19 are driven 'at a speed varial lein respectto the'lspeedcf the wheel for the cliain 27 leadingto the'shaft mounted an adhesive-applying roller 55, the

lower portion of which dips into the .adh'eg sive in the tank'and the upper portion of which serves to support the corrugated sheet F and deliver adhesiveto the crowns of the corrugations upon the under side thereof;

A. third roll of material 'Hfis mounted on suitablebrackets 56' adjacent the frame 39,,

and the sheet G as it u'nrolls therefrom,-

passes'hetween fhc-feeding rollers 52 and'5 3, and tn'eiic f over a supporting roller 57. This last-mentioned roller is adjacent the end of the steam chest 54; and its uppersurface is substantiallv in ali'nement with the upper surface of the latter, so that as the sheet G passes over said roller 57', the corrugated sheet F coming from the roller contacts directly with the upper surface said-sheet be varied.
